Title: Method for transferring information
Inventor: REBHAN RICHARD
IPC: H04N7/24
Filed: 1998-12-18
Abstract: A method for transferring information from an information provider (100) to an information consumer (190) in a highly efficient manner by means of a digital video broadcasting (DVB, 140) system and a secondary bidirectional transfer network (130). The secondary bidirectional transfer network provides information of where the DVB receiver (191) of the information consumer is located so that only suitable DVB transmitters (146) in the area are used for the information transfer itself. The location is determined by having at least one of either the transmitter frequency, the original network identification, the transport stream identification, and/or the network identification, of a transport stream of one transmitter that the receiver can receive transferred via the secondary bidirectional transfer network. Thereby only the necessary DVB transmitters need to be used for the information transfer, thus relieving the rest of the DVB transmitters (145, 147) from an unnecessary downloading.

Filed: 2000-03-16
Abstract: A method and system for allowing clients to retrieve data from data sources that do not necessarily support the same protocols and formats as the clients. The clients issue service requests. A pre-processor responds to the requests by generating XML-structured request objects with unresolved links to the data sources that have information required by the clients. An XML  processor resolves the links by issuing requests through one or more gateways. The gateways convert the responses received from the data sources into XML, which the XML processor uses to create XML composite response documents. A  post-processor filters the XML response documents, and applies XSL stylesheets to transform the XML composite response documents into client-specific responses that conform to the format required by the clients. The clients-specific responses are then sent to the clients.
